Regarding body weight, the converse is true : obesity elevates rates of preeclampsia but reduces rates of SGA. The authors assessed the combined effects of smoking and weight among US women developing preeclampsia or SGA, studying 7,757 healthy, primigravid women with singleton pregnancies in 1959-1965. Smoking (never, light, heavy), stratified by prepregnancy body mass index (BMI (weight (kg)/height (m) 2) ; underweight, overweight, obese), was examined in relation to preeclampsia and SGA. Among underweight (BMI=25), this trend was not apparent (p=0.4). Among both underweight and overweight women, smoking significantly increased SGA risk (trend p
